>I didn't do a real thorough test (I had other apps open and only ran about 4 iterations of the test). However, on a PIII 933, I got inconsistent results. In some cases IIF() was faster and in others it wasn't. Which is truly faster, however, took a back seat to the differences between the two over a million iterations. The largest amount was less than 1/10th of a second. So I would have to conclude that unless the routine was being called in excess of a million times, which is actually faster is pretty much of a moot point.

I just tried a few times with VFP 7 SP1 on a PIII 833 and a ton of stuff open. (Too lazy to shut it all down. <g>)

IF was slightly faster than IIF() for me four times running (2.4 vs. 2.1, roughly).
